Design in 3D.
Cut it flat.

Build your object from parts as thick as your material. Every slot and notch is worked out for you, then you export a DXF that is ready for the laser.

A twelve-fin lamp designed in Plyjoin, with the rings slotted onto the fins

Made in Plyjoin: 14 parts, 24 joints — one fin drawn, copied in a circle, joints computed from the geometry.

1

Compose the object

Shapes, sketches or an imported drawing, each one as thick as the sheet you will cut.

2

Say where they meet

Cross laps, finger joints and slots are cut from the real geometry — and follow the parts when you move them.

3

Export and cut

Parts laid out on the sheet, clearance and kerf already compensated. DXF or SVG, mm or inches.

Everything a flat-pack design needs

No CAD background required. If you can drag a rectangle, you can build an interlocking object.

One thickness, everywhere

Switch from 3 mm to 5 mm and every part, slot and tab is recalculated. No rework.

Joints that think

Move a part and its slots move with it. Tabs, cross laps and through slots, with clearance you control.

Copy in a circle

Rosettes, mandalas, lamps: repeat a part around an axis and edit them all at once.

Curves, not just boxes

Draw polylines and Bézier curves, cut a word as a part, or bring in an SVG you drew elsewhere.

DXF your machine likes

Closed polylines on a CUT layer, part names on LABELS, kerf compensated. Millimetres or inches.

Nothing to install

It runs in your browser, on your computer. Your projects stay yours — download them any time.

The Plyjoin workspace: shapes on the left, 3D view in the middle, joints on the right

The whole tool on one screen: parts on the left, the object in the middle, joints on the right.

Sheet layout

Your parts, already laid out

Press export and every part is nested on the sheet with the spacing you chose — clearance and kerf compensated, holes and notches exactly where the joints put them. Tell it the size of your laser bed and the parts are split into as many sheets as they need, one file each.
